"Note Body/Contents/Attachments - The body/contents of the note is stored on the SD card instead, in the "Evernote" folder on your card. So if you have a note with a 20MB PDF that you download, that will be stored on the SD card."

The problem is, I don't see an "Evernote" folder anywhere.

I searched the entire SD card for jpeg files (searching for both *jpeg and *jpg files). One way I searched was using the file manager on my tablet. The other way was by connecting the tablet to my PC via USB, so that the PC recognized it as a storage device; and then searched using Windows Explorer. Both searches found photos, but neither found the photo in question.
